To an whom it may concern..-

Be itknown that I, Mourns I-I nsHrmLD, a citizen of the United States, and res dent of the city. of New York, county of Kings,

and State of New York, have invented a cer-.

tain new and useful Improvement in Resilient Treads for Shoes, of which the following is a. specification. Y

My invention relates to resilient tread surfacessuch asare commonl applied to the soles and heels of shoes an is characterized by a simple arrangement whereby the tread surface may be rapidly and conveniently attached and detached from a shoe andi-ts shape and contact with the shoe parts secured and maintained.

Heretofore resilient soles and heels have usually been secured to shoes by means of nails or possibly by stitching thus requiring the services of a shoemaker not only for initially attaching but also for interchanging them from one shoe to another when they have worn down unevenly as is usually the case.

-Difliculty has also been heretofore experienced in providing a tread member which would maintain its shape and lie in close contact with the bottom of the shoe as the nailing or stitching had to be placed some distance in from the outer peripheral edge so as to allow for sufficient material to obtain a hold for the attaching means. The result was, particularly in the case of resilient soles, that the edges of the tread sagged producing an unsightly appearance and permitting the entrance of dirt and water, causing a deterioration of the shoe sole, discomfort to the wearer and increased wear of the resilient tread.

The above disadvantages have been almost entirely overcome in the structure shown in the accompanying drawings forming part of my application, in which Figure 1 shows a bottom plan view of one example of my invention; Fig. 2 shows a section of Fig. 1 on the line 22; Fig. 3 shows a section of Fig. 1 on the line 33 and Fig. 4 shows a section of Fig. 2 on the line 4-l.

A resilient heel, and the same arrangement may be adapted to soles, is indicated in its entirety by the numeral 5 and comprises a.

shoe. Theplate 8.11asa peripheral-"flange 11 TED S ES TPAIENT FFICE.

providedwith a plurality of. openings 12,

the purpose of which will more fullyap-r pear hereinafter. Instead of employing openings as 12 I- may employ. notches in the peripheral edge of said plate 8.

Screws l3:are adapted to pass through the holes 10 and press the crowned portion 9and peripheral flange 11 toward the shoe to which the heel is secured as is readily apparent from the drawing.

In making my heel I out two resilient ;-1nembers as 6 and, 7 to therequired shape,-

and then place the plate 8 above referred to between the resilient members and vulcanize the heel thus formed. The openings 12 permit the resilient members 6 and 7 to form resilient bonds 14 through the plate 8 thus integrally uniting the resilient members to each other. In case I employ notches as above referred to the bonds will be located on the periphery of the tread thus overcoming any possibility of the tread sagging as hereinbefore described. It is often desirable to have the resilient members slightly larger in diameter than the steel plate. I therefore prefer to manufacture my heel with the said resilient members extending beyond the peripheral edge of the metal plate. In this case the edges of the resilient members are also united in the vulcanization forming an integral unit which forms a substantial, easily attached and detached heel when worn.

The lower member 6 may of course be provided with screw openings which register with the openings 10 of the plate 8 before the resilient members 6 and 7 are vulcanized to each other, and in case I desire to provide such openings, which give a more finished appearance to the heel or sole, I provide such openings when the lower member is prepared, c. g. with a suitable die. The provision of a screw opening, however, is not necessary as it usually is possible to detect the position of the openings 10 by the slight circular depressions on the median line of form a tread of stratified resilient and rigid material; hence When I speak in my claim of a member I do not mean that the member need necessarily be a separate and independent member and when I speak of openings in the plate I mean also to include notches.

When I speak in my claim of two resili-' ent members united over a plate I also mean to include a single member which has been partially slit and the plate introduced therein.

As it is obvious that my improved tread may be used upon the sole of the shoe or Copies of this patent may be obtained for five cents each, by addressing the (Commissioner of Patents,

' heel in the claim,

my hand. upon both the sole and heel as Well as upon the heel alone, Iintend, when I use the word 1 that it shall include the Word sole as Well.

I claim: A tread for shoes comprising a plate ha ing a central recess and a peripheral flange outside of said recess and being provided with a series of openings located at spaced intervals on said flange and With apertures in said recess for the accommodation of fastening devices, said plate being otherwise of unbroken continuity, and a heel of resilient material completely embedding said plate.

andfitting in surface contact with theopposite faces of said recess and said peripheral flange, said heelhaving a series of'integral bonding portions extending through said series of openings transversely to said plate. 7
